PHILIP HENRY ONEILL, OF BROOKLYN, NEYV YORK.

WEIGHING SCALE.

SPECIFICATION folming part of Letters Patent No. 347,056, dated August10, 1886.

Application filed January 18, 1886.

To aZZ whom it may concern:

Beit known that I, PHILIP HENRY ONEILL, St. Marys l'iospital, St. Marksavenue, of Brooklyn, in the. county of Kings and State of New York, haveinvented a new and useful Improvement in .llcanrScales, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

My invention consists of a beam-scale designed to sustain and recordfrom one-half to six ounces, by half-ounce graduations, that can becarried in the pocket. When in its leather case (see l igu re 21, it istwo inches wide, live inchcslong,aiul less than three-eighths of an inchin thickness, weighing less than two ounces. it is composed of threeseparable parts: First, the indicator A; second, the disk 13 and thebeam 0, and, third, the objectholder D. The upper portion of A isgrasped by the thumb and forefinger of the right-hand, and the wholescale held so suspended while in use.

Fig. 2 shows the shape of A before a halfturn is made (giving it theappearance shown in Fig. 1) to enable it to slide on the beam andpresent itself llatwise in conformity with B, and that the corners a and7), Fig. i, may act as a check on the beam 0 when off a true balance.

By adji'istinp; the lower portion, A, Fig. 2, to the scores or notchesin the bottom of O and referring to the corresponding marks on the facethewcight of the object is ascertained. If the object is overweight, thedisk will rise, and vice versa. The lower potrion, c, Fig. 1, of thispart of the scale also serves as the fulcrum, and is movable to anylocation on the beam, and must be shifted to the various notches toascertain whether the object is over or under the weight thereindicated.

The disk l is the connterbalancc-wcight. By adjusting the fulcrum r atthe point- :r on the beam the empty scale is maintained in equilibrium.it is also the counterpoise when an object is being weighed, made so bythe Serial No. 188,869. (No model.)

moving of the fulcrum c to other locations on the beam. It is at alltimes stationary. The other portion, 0, of this part of the scale isconstructed with scores or notches in its lower edge corresponding tothose appearing on its k face to receive and retain the fulcrum. Thecounterpoise being stationary and the fulcrum movable,these notches willnot be equidistant, but will vary in the manner represented in theannexed drawings. The lower left-hand corner of O is bored large enoughto admit the obiect-holder D to pass through and have free action.

The retention of a letter in the object-holder is accomplished byinserting the envelope fiatwise between the arms of the spring-clamp at(Z, the hook e to be used for packages, newspapers, &e.

I am aware that there are numerous varieties of beams patented and inuse, but they are fitted with a movable counterpoise-weight, which, inmost cases, must be augmented as the weight of the object being weighediiiereases, and that without exception they have the stationary fulcrum,whereas my invention consists of a scale constructed in a differentmanner, having a movable fulcrum and stationary counterpoise. Therefore,

\Vhat I claim, and desire to secure by Let tors Patent in the UnitedStates, is-

in a weighing-scale, the combination of a beam, (l, having acounter-weight, 1 at one end and rigid'with said beam, an object-holderattached at the other end, with an indicator, A, in which said beamslides, all substantially as described.

In testimony whereof Ihavesigued my name to this speciiicatioinin thepresence of two subscribing witncsses, on this 13th day of January, A.D. 1886.
